Captive Purity

The key component for any reverse osmosis unit is its membrane. The membrane will determine the type of contaminants removed and how much water the unit will produce. Our Captive Purity Hi-S (High Silicate) membranes are the gold standard and will remove 96% of nitrates and up to up to 99.5% of silicate. Chlorine will ruin TFC, Hi-F, and Hi-S membranes so prior carbon filtration is required. All Captive Purity Membranes and RO and RO/DI units are designed and manufactured in the USA.

Please note that these Hi-S replacement membranes are interchangeable with Kent Marine, and SpectraPure RO or RO/DI unit. We have researched and tested the best replacement membranes among all manufacturers, and offer only the best available.


Manufacturer Info

The brand is best known for their high-quality line of reverse osmosis filter systems and accessories. Captive Purity also produces refractometers for testing salinity, portable pen-sized meters for testing pH as well as replacement filter media for their RO and RO/DI filter systems.

Works fine

I have no way of measuring the TDS on these, but I replace them every year or so depending on my usage and keep a variety of coral and fish with bright LED lights and very little algae growth and no detectable phosphates. This membrane appears to be working as it should.

RO filter

I bought this unit to replace my spectrapure 90 GPD Filter. I have a 4 stage RO/DI filter and replaced the Other 3 filters also. We have well water where I live and This unit has been great. The new RO filter is working As I expected! So far I've only had to produce a 6 gallon Bucket of top off water. Only took 1 hour and 20 minutes! My TDS meter read 0 on the output end! I'm happy with it and would recommend it to others

Price was lowest found, it installed easily, and the water output from it registered 0 on the TDS meter. What else could you want?
